Specification of Letters Patent.

Patented July 23, 1918.

Application filed September 22, 1915. Serial No. 52,049.

To all whom it may concern:

Be it known that I, EMILIO ALBERTI, a citizen of the United States, anda resident of the city of New York, in the county of Kings and State ofNew York, have invented certain new and useful Improvements in IVood-TopCorks; of which the following is a specification.

The present invention relates to bottle stoppers, and more particularlyto headed stoppers or, as they are called in commerce, wood-top corks.

Stoppers of this type are usually made of two parts, to Wit: a body ofcork or the like and a wooden head of enlarged dimensions, so as topermit the stopper to be grasped by the hand to be withdrawn from themouth of a bottle without the aid of a cork-screw, thereby facilitatingthe operation of removal, and also rendering it capable of re peateduse. In one type of these corks there is provided in the underface ofthe wooden head a circular recess, which is adapted to,

receive the upper portion of the stopper body, the latter beingpermanently secured in said recess by a suitable cementing medium. Inpractice it has been found that, when the cork body is driven into therecess in the wooden head, the cementing medium or the larger partthereof is squeezed out from said recess, so that an imperfect union isformed between the two elements of the stopper, with the result that,when the stopper is being withdrawn from a bottle, the head thereof willalmost invariably separate from the body portion of the same, and thelatter will be left in the bottle.

The main object of the present invention is to obviate the defect abovementioned, or in other words to producea wood-top cork wherein theseparation of the elements is rendered impossible, or at least to alarge degree impossible.

With these and other objects in view, which will more fully appear asthe nature of the invention is better understood, the same consists inthe combination, arrangement and construction of parts hereinafter fullydescribed, pointed out in the appended claim and illustrated in theaccompanying drawings, it being. understood that many changes may bemade in the sizeapd proportion of the several parts and details ofconstruction within the scope of the appended claim without departingfrom the spirit or sacrificing any of the advantages of the invention.

Two of the many possible embodiments of the invention are illustrated inthe accompanying drawings, in which t Figure 1 is a vertical centralsection taken through a headed stopper made in accordance with thepresent invention; Fig. 2 is a of this tapering body is attached a head11,

made of wood or similar material. This head is shown in the drawings asbeing diskshaped, but may, obviously, be ofany other configuration tosuit the requirements. In the underface of the head is formed a circularrecess 12, said recess being preferably undercut and adapted to receivethe upperportion of the body 10. That face of the recess 12 which issubstantially parallel to to the top face of the head is corrugated, asindicated at 13, said corrugations running, for instance, inconcentrical" circles, as shown in Figs. 2 and 3 of the drawings, thealternate ridges and furrows being disposed fairly near to each other,or being placed more apart as in the modification shown in Fig. .t ofthe drawings. The body and head of the stopper are united by aninterposed suitable cementing material 14, for instance glue. The tapersof the conical body and of the recess 12 may be the same, or the saidtapers may be different, the taper of the re cess being in the lattercase smaller. than that of the stopper body, with the result that theupper portion of the stopper body is held within said recess in asomewhat compressed state, so that the two parts are more firmly kepttogether.

In assembling the elements of the stopper,

they are brought intoregistering position in alinement with a plunger,the cementing medium having been previously inserted into the recess inthehead element. That portion of the stopper body which is to be seatedin the recess is then compressed and forced by the plunger into therecess, wherein said portion expands. Inasmuch as corrugations areprovided. in the recess, the cen'ienting medium in the furrows of suchcorrugations will not be forced out of the recess when the stopper bodyis driven thereinto, whereby a firm union between the two elements ofthe stopper is obtained. The stopper herein described is thus free fromthe objections of the wood-top corks heretofore used, as its head willnot separate from the body portion when it is withdrawn from the mouthof a bottle in which it has been originally tightly fitted.

It is obvious that, while herein the stopper body has been described asbeing made in the form of a frustum of a cone, cylindrical bodies may bejust as well employed. Itis to be observed furthermore that, in stead ofthe symmetrically arranged corrugations 13, there may be provided in there cess in the stopper head depressions, indiscriminately disposed onthe entire or part of the plane face of the recess, or the said planesurface may be roughened for the purpose described. The corrugations,depressions or roughing serve as collecting receptacles or pockets, asit were, from which the adhesive material cannot be driven out by thestopper body in assembling.

What I claim is Astop per comprising a tapered body of cork or the like,a head or flange having a recess in which a portion of said body isseated, the taper of said recess being smaller than that of said stopperbody, said recess being provided with depressions, and a cementingmedium in said recess and depressions for uniting the said elements.

Signed at New York, in the county of New York, and State of New York,this 31st day of Aug, A. D. 1915.

EMILIO ALBERTI.
